Supplementation with calcium and/or vitamin D did not reduce fracture risk in older adults.
Contrary to current opinion, a systematic review of 33 randomized trials in about 50,000 community-living adults over 50 years old found no benefit for supplementation of vitamin D and/or calcium. This study strongly supports the U.S. Preventive Services Taskforce in not recommending calcium or vitamin D supplementation in this population.
PositiveTip: Get your vitamin D from adequate sun exposure, exercise daily, and include plenty of calcium rich foods in your diet.
Does every "body" really need milk?
An observational study in Sweden of over 100,000 men and women, followed for 13-22 years, found that high consumption of milk was associated with increased mortality and, in the women, higher risk of fractures. Women who reported drinking 3 or more glasses of milk per day nearly doubled their death rate from any cause compared to those who drank less than 1 glass per day. The authors caution that more research is needed.
PositiveTip: Excessive use of milk could be problematic. As always, moderation is vital.
Football a dangerous sport for 12-17 year olds.
A study of football injuries in children ages 6-17 between 1990 and 2007 found that the majority of injuries (78%) occurred in the ages 12-17. The most frequent type of injury was sprains and strains (31%), followed by fractures and dislocations (28%), and soft tissue injuries (24%). There were 8631 concussions annually! Total injuries actually increased from 274,094 in 1990 to 346,772 in 2007.
PositiveTip: Parents should make sure proper safety precautions are in place at school or discourage their children from playing contact sports.
High Calcium Intake May Actually Increase Risk of Hip Fractures
A newly published Swedish study of over 61,000 women who were followed for more than 19 years provides the strongest evidence to date that high calcium intake is not beneficial for preventing bone fractures. The exceptions are women with very low amounts of calcium and vitamin D in their diet. Women in the top 25 percent of calcium intake showed no reduced risk of fractures or osteoporosis. Instead, they actually showed a 19 percent increase in hip fractures. The lowest fracture risk was found in women with total calcium intake of about 800 mg per day.
Lots of people are urged by their doctors to take Vitamin D supplements to preserve strong bones. But a study published today in the Journal of the American Medical Association reports a surprising complication from vitamin D supplements.
